One PDF at a time

What is it?

This tool rotates every page of a PDF by a fixed angle — 90, 180, or 270 degrees — entirely in your browser.

Formula Explanation

Each page in a PDF stores a rotation value alongside its content. This tool adds your chosen angle to each page's existing rotation (wrapping at 360°) rather than re-drawing the page content, so nothing inside the page is altered — only how it's displayed and printed.

Example Calculation

A landscape-scanned page that displays sideways can be fixed by rotating the whole PDF 90° clockwise (or counter-clockwise, using 270°) so every page reads upright.

How to Use

  1. Click the upload area or drag and drop a PDF file onto it.
  2. Choose a rotation angle: 90°, 180°, or 270° clockwise.
  3. Click Rotate & Download to save the rotated PDF.

Benefits

  • Fixes sideways or upside-down scanned pages without installing any software.
  • Processes everything locally in your browser — files are never uploaded anywhere.
  • Rotates the whole document in one click instead of page by page.

Use Cases

  • Fixing a PDF scanned in landscape orientation so it reads upright.
  • Correcting a document that was scanned upside down.
  • Rotating a whole PDF before printing to match your printer's expected orientation.

What Your Result Means

The downloaded PDF has the same page count and content as the original — only the display/print orientation of every page changes by the angle you chose.

Tips

  • If a page still looks wrong after rotating 90°, try 270° (the opposite direction) instead.
  • This rotates every page by the same angle — it isn't currently possible to rotate individual pages differently.
  • 180° is useful for a PDF that was scanned completely upside down.

Common Mistakes

  • Rotating 90° when 270° was needed (or vice versa) — if the result looks wrong, try the other direction.
  • Expecting individual pages to rotate differently — this tool applies one angle to the whole document.
  • Trying to rotate a password-protected PDF, which this tool can't open.

FAQs

Are my PDF files uploaded to a server?

No, all processing happens locally in your browser using JavaScript — your files never leave your device.

Can I rotate only some pages, not all of them?

Not currently — this tool applies the same rotation to every page in the document.

Does rotating change the file size or quality?

No, rotation only changes the page's display orientation metadata — the underlying content is untouched, so quality and file size stay essentially the same.

Can I rotate a password-protected PDF?

No, encrypted or password-protected PDFs can't be read by this tool — remove the password first using your PDF reader.

Files are read and rotated locally in your browser and are never uploaded to a server.
